Specification of Letters Patent.

Patented Feb. 14, 1922.

Application filed July 15, 1919. v Serial No. 311,063.

To all whom it may concern:

1 3e it known that I, JOHN A. RYMER, a citizen of the United States, and a resident of Oakland, county of Alameda, State of California, have invented certain new and useful Improvements in Processes Y for Enameling 00d or Metal Surfaces, whereof the following is a specification.

This invention relates to a process for enameling wood or metal surfaces.

The accompanying drawing forming part of the specification illustrates the body and the coatings of materials, the same bearing legends to indicate what they represent.

, In carrying out the invention I proceed as follows, viz :If the surface is an old one, that is, one that has been painted or varnished before, I first remove all old paint from the surface, by any suitable method. I then wash the surface with gasoline or alcohol to kill the effect of the paint orvarnish removed. .If the surface is metal, I now treat it with a metal primer which has an elastic and adherent quality. \Vhen this prinier is thoroughly dry, if the surface is rough, I build it up with a putty made of lacquer and dry white lead, and when it is thoroughly smoothed, I coat it with japan color of the color which it is to finally have. This coating I repeat as often as necessary to produce a solid color. intermediate or protection coat, which is to be made of straight japan, or japan and 'litharge (a half pound to the gallon) and japan color the same as before. This coating is best sprayed on, and all partsshould be thoroughly covered. I then proceed as follows: I then take. of celluloid enamel, or

similar enamel, one-third enamel, one-third lacquer and one-third slow drying thinner. I spray the entire surface with this mixture, and when dry rub itto a dead smooth finish, and repeat the treatment till the desired gloss and finish is acquired. The surface may then be rubbed with pumice stone and water.

by rubbing with pumice stone and water.

I then apply an 7 modified without departing from the spirit thereof.

It is to be understood that certain terms employed in this specification are those which designate certain well known articles of commerce in the painters supply trade.

The term metal primer refers to a composition inwhich linseed oil. red lead and turpentine are ingredients. The term lacquer used herein is understood to be a composition, the base of which is celluloid treated with amyl acetate oracetone. The term japan color refers to a coating, comprising a pigment such as drop black, parisian blue or the like-ground in nonpareil japan. Slow drying thinner is composed of acetone and castor oil in approximately the proportions of one-half ounce of castor. oil to a gallon of acetone.

What I claim and desire to secure by Letters Patent of the United States, is the following, to wit 1. The process of treating surfaces which consists in priming the surface, then treating it with japan color one or more times, then giving it an intermediate coat containing japan, and then treating it one or more times with a mixture containing one-third celluloid enamel, one-third lacquer and onethird slow drying thinner, and rubbing after each such treatment.

2. The process of treating surfaces, which consists in priming the surfacepsmoothing it with lacquer and dry white lead, treating it one or more times with japan color, giving it an intermediate coat containing japan, and treating it one or more times with a mixture containing one-third celluloid enamel, onethird lacquer, and one-third slow drying thinner, and rubbing after each'treatment.

3. The process of treating surfaces," which consists in priming the surface and smoothing the same, then coating it one or more times with japan color, then spraying it with an intermediate coat containing japan, then spraying it one or more times with a mix- In fesfimony that I claim the foregoing ture containing one-third of celluloid I have hereto set my hand this 21st day of enamel, or similar enamel, one-third lacquer J une, 1919, in the presence of Witnesses.
